, M l CHARLES I. LATTIG, OF ROCHESTER, NEW YORK, ASSIGNOR, BY MESNEASSIGNMENTS,

TO LANGSLOW-FOWLER COMPANY, OF ROCHESTER, NEW YORK. A CORPORATION OF NEWYORK.

Ap'piicatiorifaied April 14. 1913.

Be it known that l. CHARLES I. LATTIG, a citizen of the United States`residing at Rochester, in the -county of Monroe and State of New York,lhave invented certain new and useful Improvements in School- Chairs;and I do hereby .declare the following to be a full, clear,.and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part of this specification, and to thereference-numerals marked thereon.

My present invention hasfor its object to provide an improved form ofcombined chair and writing desk, which is partlcularly adapted to beused as a study or School chair, the parts of which areadjustable toaccommodate persons of different stature.

My invention has .for its further object to provide an improved-framingconstruction adapted particularly for chairs of this charactor,consisting in the positioning of Aone of the front legs of the chairahead of the forward edge of the seat for the purposegof increasing thestability of the chair and rendering it less liable to be overturned.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings:

Figure l' is aside elevation of a chair constructed in accordance ,withmy invention 2 is a front elevation thereof;

Fig. 3 is atop plan View` the desk lid being' removed, and shown in planView in Fig. 4;

Fig. 5 is an enlarged detail, vertical, scctional viw taken on the line.mh-5X of Fig.'

l, and

Fig. 6 is a similar view taken on the line 6 `6x of Fig. 5.

Similar reference numerals in the several gures, indicate the sameparts.

In carrying out my invention it may be. applied to any particular typeor style of chair, the essential elements of Which are shown in theillustrations as comprisethe seat l and the front and rear pairs of legsa:a,1 b-b respectively. The rear legs are connected by the rail 'orframe piece b2 and they are each connected with one of the l Specicatonof Letters Patent'.

pieces c -fo which are of unequal length, the longerone being preferablylocated at the right hand side of the structure sov as to position theleg a somewhat in advance shown particularly in Fig. l, thus ln'ov'idinga forwardly projecting bearing or support in advance of'the forward edgeof the seat l. The usual front frame piece of the chair Seat frame,indicated by extends beneath the forward edge of the seat parallel tothe rail L2, its ends being mortised or otherwise secured to theinnerface of the rail 0 and the inner edge of the yleg a. lThe seat l ispreferably made solid wood and at one edge is provided with theforwardly extending projection l", which overlaps the inner edge of theleg a and to which it is securely united` this arrangement affording abrace or bracket,vwhich materiallystitfens the upper end of said leg.The latter may also be further braced by a bracket (Z secured to theface of the rail (l near its lower edge as shown in Fig. 2.

The desk or writing table yindicated by chair seat and the end of thetically a short to afford a chair leg a 1s projected 'verdistanceasindicated by a2 and also spaced therefrom and parallel to the leg 1s aframe piece a which is secured to the outer face of the rail c. itsupper end being united to the upper extremity of the leg a by a crossplate a". The leg (1 and the frame m3 are. preferably made rectangularin cross section so that their Side faces', and front and rear edgescombine to form parallel angular guides on which is movably mounted thevertically adjustable support on which the desk is mounted.

The support for the desk comprises the vertical angle iron strips f-fjoined at their lower ends by the strap f2, having their upper ends f3and f4, respectively, bent into a horizontal position and extendintransversely across the front of the chair. The portions f-f of thesupport are connected at their upper ends by an angle iron guide g andtheir laterally projecting ends fa-f* are similarly connected by a guideg', said guides being arranged parallel and extending forwardlyrelatively` to the cha-ir seat.

he support is further strengthened by a plate h riveted to the -parts f8and f4 and and constructed of.

corner bracket plates -i extending over the outer faces of the angleirons and riveted thereto, as shown inthe several figures. The desk 2 isadjustably secured in position by rails k and k', which permit it to beadjusted either forwardly or rearwardly, 'as desired, the limitation ofthis movement being determined by a stop member Z attached to the underside of the desk and coperating with the' adjacent edges of thesupporting members f3 and ff, as shown in dotted lines in Fig. et, andfull lines in Fig. 6.

The vertical adjustment of the desk is preferably obtained by clampingnuts on the bolts ln-m carried on lthe leg. ay and guidel piece a3,which project through elongated slots or apertures in the supportingmembers f--f, shown particularly in Fig. l.

i A chair constructed Ain accordance with my present invention possessesva particular advantage in that a iirm and rigid construetion isprovided for the support of the desk which is disposed centrallyof oneend thereof and as the support itself comprises parallel members Whichare spaced apart, it .is capable of withstanding thetivisting ortorsional strains resulting from shifting the chair by grasping thedesk, by carelessness on the part of the user when seating himself or inattemptingto arise from the chair; or by reason of the load which may beapplied to the desk; further, an important function may be ascribed tothe positioning of the leg underlying the desk lid at a point' inadvance of the other front leg of the chair, since this separates thebearing points on Which the chair rests and affords additional stabilityto the structure without requiring greater iioor space than must beallotted to an ordinary chair equipped with a desk. attachment.

I claim as my invention:
